1. Instrument Overview
1.1 Instrument
Overview
eZwestTM Lite is a fully automated blotting device that frees researchers from the
manual labor of traditional western protocol. eZwestTM Lite can be programmed to
run a sequence of western blot membrane incubation steps automatically including:
blocking, primary antibody and secondary antibody incubations and washing. When
desired, the primary antibody can be recovered for re-use. The processed
membranes are ready for detection. Automation of the incubation steps minimizes
errors and variability typically associated with manual operations contributing to
experimental reproducibility.
The eZwestTM Lite device is compatible with the traditional reagents and protocols
used for conventional western blotting. No proprietary reagents are required. Fully
customizable steps and solutions make eZwestTM Lite a powerful tool fitting specific
experiment needs for both routine and novel western blotting conditions.
